Leviton Telcom OSSMD-GDT Wall Box Occupancy Sensor

Product Description

The LEVITON TELCOM OSSMD-GDT is a wall box occupancy sensor designed for no-neutral wiring configurations. Occupancy sensors in this category detect room presence and automatically control connected lighting circuits, switching loads on when occupancy is detected and off after a set vacancy period. The no-neutral design allows installation in switch locations where only a hot and a switched-leg conductor are available, which is a common condition in older residential and light commercial wiring. Licensed electricians and qualified controls technicians install this sensor as a direct wall box replacement for a standard single-pole switch.

This sensor is suited for residential and light commercial applications where energy-efficient automatic lighting control is required without access to a neutral wire at the switch location. Typical install scenarios include bedrooms, offices, conference rooms, hallways, and utility spaces where a standard wall box switch is already present. The unit ships individually and is categorized as a hardware accessory controls component.

Key Features

• No-neutral wiring configuration — installs in standard switch boxes without a neutral conductor
• Wall box form factor for direct replacement of single-pole switches
• Occupancy-based automatic load control for lighting circuits
• Single-unit packaging for individual replacement or retrofit installations

Compatibility

Designed as an OEM-style replacement for wall box occupancy sensor applications in residential and light commercial lighting control systems where no-neutral switch wiring is present.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit at the breaker panel and verify absence of voltage with a meter before wiring. The no-neutral design eliminates the need to run an additional conductor, but verify the existing switch loop configuration is compatible before beginning work. Do not exceed the sensor's rated load capacity for the connected lighting circuit.
